Technical Characteristics
Developed for stable control needs
LKF-MTG200 3-axis MEMS gyro combo is a highly reliable and cost-effective 3-axis MEMS inertial sensor, which can be widely used in the fields of navigation, control and measurement represented by attitude stabilization. The MEMS gyroscope with high bandwidth, low latency and low noise is used inside the system, and it has a good mechanical environment adaptability, which can provide stable control of complex products.
High-precision device manufacturing and system calibration compensation technology
The company has accumulated a series of key technologies during the research and development of this project to ensure the high performance of the product. Meanwhile, the system adopts high-speed sampling, static error compensation (bias, scale factor, installation error, etc. for the whole temperature range), dynamic error compensation and other technologies to ensure that the product obtains the best performance in the process of user's use.
The LKF-MG200 3-axis MEMS gyro combo system utilizes a high bandwidth, low latency, low noise MEMS gyro inside the system and can maintain its performance in a wide range of temperature environments, a large number of levels of vibration environments, and can provide accurate angular motion information for stabilizing and controlling the servo system with a guide head.
